Whether you are protecting hillsides, homes and businesses, roads or trying to control and divert floods through sandbags, there is a easier and faster way using either our ground bladder technology or compost filter socks/blankets.

Instead of bags and sand, our bladder fills up with water to create a barrier anywhere you need it. What would be a five-hour job with a team of workers can be accomplished in 30 minutes by one or two people.

Interceptor Check Dam -
The Next Generation of Bladder Technology

Geotextile Bladder vs. Interceptor Check Dam.
In essence, the similarities between the two are that they both have water bladders as the primary cofferdam.

But where a geotextile sock covered bladder will hold and collect the stormwater; a contractor will need to supply a dewatering pump and an electrical source with an automated start/stop controls to route the impounded stormwater around the construction work area.

Whereas, the interceptor check dam will allow the impounded stormwater to flow out its control point consisting of a cinch strap in the middle of the bladder where an outlet port is located. Preferably the hose can be routed via gravity around the construction work area; thus making it a hands-free operation independent of power and/or pumps. If the discharge point is above the hydraulic gradient; then a pump station will still be needed.

The installation of the interceptor check dam is fairly simple. It comes out typically as a rolled-up unit of which it is just placed across the culvert and folded out into position. The upstream edge has grommets to stake down. The bladder is then filled with the back wall clipped into the front fish/debris screen which is strapped to the staked grommets. As the bladder fills up, the interceptor check dam starts taking shape and impounding stormwater. Since the debris screen will remove the large solids, the discharge hose is protected from plugging.

For breaking down the interceptor check dam, disconnect the hose and open up the outlet valve for dewatering the impounded stormwater. Note that there is a small apron on the downstream edge for draining; however, the drainage course will be to be protected for erosion control. When that flow has initially diminished, then open up the drainage port(s) of the bladder and allow it to deflate. When the bladder is nearly empty, unstake the interceptor check dam and roll it out of the culvert.

Both designs can be pressure washed, dried out, rolled up, and placed into inventory for later use.

Advantages of Using Ground Bladder Technology

Hillside Covers:Ground bladder technology can use far less labor, last 10+ years, prevent wind from lifting sheeting to billow wherever, and be removed, deconned & reinstalled in no time.

Flood Control:In no time and with less labor - ground bladders can be easily installed to protect buildings, doorways, land, and equipment from flood events.

Cofferdam:In shoreline construction projects, it is necessary to perform the work in a semi-dry environment. Our ground bladders can segment out sections of shoreline from the rivers, lakes, ponds, and/or oceans.

Check Dam:For installing culverts, utilities, bridges, shoreline rehabilitation, and landscaping; ground bladder technology with our patented design will check dam the entire flow and divert to a location deemed fit – typically in less than 2 hours for 2 guys. The diverted flow can be treated for sediment and/or contamination before returning to its original course.

Temporary Building Walls with ClimaCover Clips:Building Contractors find it necessary to wall off sections of the buildings for reducing drafts and increasing the worker productivity in frigid
environments. Visqueen walls can be installed, removed, and reused at a different location a fraction of the time and expense.

Road Saver:Sometimes water streams develop suddenly off the hillsides and threaten the road/highway integrity. Our ground bladder technologycan coffer dam the stream and direct the water to cross the road on a controlled matter.

Dike Boil Buster:It is typical for dikes to develop at times leaks that will need to be fix immediately. Our boil buster will not only stop the leaks; but also allow the internal sediment to completely fill-in the channel causing the leaks. This ground bladder
technology can then be moved to the next leak easily.

Emergency Roof Repairs:Buildings that are missing section(s) of their roofs can use visqueen sheeting with ground bladder technology to add a protective cover over that missing section(s) without putting any holes into the roof.

Large Tent Supports:At times there is a safety and an aesthetic value of not having stakes in the ground and tie lines for tent support. Weighted ground bladders can hang from the upper crossbars and hold the tent in-place during windy days.
